These were unnecessary for a couple of reasons, but it seems like the
old code went through a lot of effort to avoid duplicating the code to
print a RECT, even though the windowrc gets printed anyway at the end of
the function.
Avoid printing the same windowrc twice by only printing it when it gets
changed (in the w32->current_fs branch.)
This makes the default fit on screen, autofit and window-scale
changing behavior to use the screen working area, instead of
the whole screen area.
As a result mpv window doesn't cover the taskbar now when opening
videos with size larger than the screen size.
The actual behavior now is the same as expected behavior for
usecases 1-4 from #4363.
This commit also removes the screenrc from w32 struct.
The screen rect can now be retrieved via `get_screen_area` function,
which was renamed from `update_screen_rect`.
On a multi-monitor system, if the user moved the window between
monitors, this function will return the current screen area under
the window, and not the screen area from monitor specified by
`--screen` option. The `--screen` option sets the initial monitor
the mpv window is displayed on.
I suppose this doesn't matter in practice, i.e. even if calls relayed
over the dispatch queue will cause WndProc to be invoked, WndProc will
never run for a longer time.
Preparation for removing recursion support from the dispatch queue code.
Refactored and split the `reinit_window_state` code into four
separate functions:
- `update_window_style` used to update window styles without
modifying the window rect.
- `fit_window_on_screen` used to adjust the window size when it is
larger than the screen size. Added a helper function `fit_rect` to
fit one rect on another without using any data from w32 struct.
- `update_fullscreen_state` used to calculate the new fullscreen
state and adjust the window rect accordingly.
- `update_window_state` used to display the window on screen with
new size, position and ontop state.
This commit fixes three issues:
- fixed#4753 by skipping `fit_window_on_screen` for a maximized
window, since maximized window should already fit on the screen.
It should be noted that this bug was only reproducible with
`--fit-border` option which is enabled by default. The cause of the
bug is that after calling the `add_window_borders` for a maximized
window, the rect in result is slightly larger than the screen rect,
which is okay, `SetWindowPos` will interpret it as a maximized state
later, so no auto-fitting to screen size is needed here.
- fixed#5215 by skipping `fit_window_on_screen` when leaving fullscreen.
On a multi-monitor system if the mpv window was stretched to cover
multiple monitors, its size was reset after switching back from
fullscreen to fit the size of the active monitor. Also, when changing
`--ontop` and `--border` options, now only the
`update_window_style` and `update_window_state` functions are used,
so `fit_window_on_screen` is not used for them too.
- fixed#2451 by moving the `ITaskbarList2_MarkFullscreenWindow`
below the `SetWindowPos`. If the taskbar is notified about fullscreen
state before the window is shown on screen, the taskbar button could
be missing until Alt-TAB is pressed, usually it was reproducible on
Windows 8.
Other changes:
- In `update_fullscreen_state` the `reset window bounds` debug
message now reports client area size and position, instead of window area
size and position. This is done for consistency with debug messages
in handling fullscreen state above in this function, since they also print
window bounds of the client area.
- Refactored `gui_thread_reconfig`. Added a new window flag `fit_on_screen`
to fit the window on screen even when leaving fullscreen. This is needed
for the case when the new video opened while the window is still in the
fullscreen state.
- Moved parent and fullscreen state checks out from the WM_MOVING to
`snap_to_screen_edges` function for consistency with other functions.
There's no point in keeping these checks out of the function body.
When window and screen size and position are stored in RECT, it's
much easier to modify them using WinAPI functions.
Added two macros to get width and height of the rect.
* Distinguish between the window being moved or not.
* Skip trying to snap if currently in full screen or an embedded
window.
* Exit snapped state if the size changed when the window was being
moved.
Check the expected width and height against up-to-date
window placement. If they do not match, we will consider snapping
to have happened on Windows' side.
For consistency with already implemented shcore.dll
function loading in w32->api:
Moved loading of imm32.dll to w32_api_load, and declare
pImmDisableIME function pointer in the w32->api struct.
Removed unloading of imm32.dll.
Mouse wheel bindings have always been a cause of user confusion.
Previously, on Wayland and macOS, precise touchpads would generate AXIS
keycodes and notched mouse wheels would generate mouse button keycodes.
On Windows, both types of device would generate AXIS keycodes and on
X11, both types of device would generate mouse button keycodes. This
made it pretty difficult for users to modify their mouse-wheel bindings,
since it differed between platforms and in some cases, between devices.
To make it more confusing, the keycodes used on Windows were changed in
18a45a42d5 without a deprecation period or adequate communication to
users.
This change aims to make mouse wheel binds less confusing. Both the
mouse button and AXIS keycodes are now deprecated aliases of the new
WHEEL keycodes. This will technically break input configs on Wayland and
macOS that assign different commands to precise and non-precise scroll
events, but this is probably uncommon (if anyone does it at all) and I
think it's a fair tradeoff for finally fixing mouse wheel-related
confusion on other platforms.
mpv's mouse button numbering is based on X11 button numbering, which
allows for an arbitrary number of buttons and includes mouse wheel input
as buttons 3-6. This button numbering was used throughout the codebase
and exposed in input.conf, and it was difficult to remember which
physical button each number actually referred to and which referred to
the scroll wheel.
In practice, PC mice only have between two and five buttons and one or
two scroll wheel axes, which are more or less in the same location and
have more or less the same function. This allows us to use names to
refer to the buttons instead of numbers, which makes input.conf syntax a
lot easier to remember. It also makes the syntax robust to changes in
mpv's underlying numbering. The old MOUSE_BTNx names are still
understood as deprecated aliases of the named buttons.
This changes both the input.conf syntax and the MP_MOUSE_BTNx symbols in
the codebase, since I think both would benefit from using names over
numbers, especially since some platforms don't use X11 button numbering
and handle different mouse buttons in different windowing system events.
This also makes the names shorter, since otherwise they would be pretty
long, and it removes the high-numbered MOUSE_BTNx_DBL names, since they
weren't used.
Names are the same as used in Qt:
https://doc.qt.io/qt-5/qt.html#MouseButton-enum
This was attempted before in fc9695e63b, but it was reverted in
1b7ce759b1 because it caused conflicts with other software watching
the same keys (See #2041.) It seems like some PCs ship with OEM software
that watches the volume keys without consuming key events and this
causes them to be handled twice, once by mpv and once by the other
software.
In order to prevent conflicts like this, use the WM_APPCOMMAND message
to handle media keys. Returning TRUE from the WM_APPCOMMAND handler
should indicate to the operating system that we consumed the key event
and it should not be propogated to the shell. Also, we now only listen
for keys that are directly related to multimedia playback (eg. the
APPCOMMAND_MEDIA_* keys.) Keys like APPCOMMAND_VOLUME_* are ignored, so
they can be handled by the shell, or by other mixer software.
Instead of PostMessage, use SendNotifyMessage from the SendMessage
family of functions to wake up the Win32 thread from the VO thread. When
a message is sent rather than posted between threads, it ends up in a
different queue which is processed before posted messages and can be
processed in more places. This prevents a playback glitch when clicking
on the titlebar, but not moving the window. With PostMessage-based
wakeups, VOCTRLs could be delayed for up to 500ms after the user clicks
on the titlebar, but with SendNotifyMessage, they still complete in
under a millisecond.
Also, instead of handling WM_USER, process the dispatch queue before
every message. This ensures the dispatch queue is processed as soon as
possible. WM_NULL is used to wake up the window procedure in case there
are no other messages being processed.
This seems to reduce glitches when resizing a --wid program (or it could
be a placebo.) Since we don't need the WM_WINDOWPOSCHANGING handler in
--wid mode, it should be fine.
This was added in 3f268cc4f2 because it wasn't clear whether
WM_NCCREATE could be used to send a context pointer from CreateWindowEx
to the window procedure. WM_NCCREATE isn't always the first message sent
to a window, but this seems to be because of an undocumented but
well-known bug where, for top-level overlapped windows, a spurious
WM_GETMINMAXINFO arrives first instead. The WM_GETMINMAXINFO can be
safely ignored, so it is still okay to pass the context struct in
WM_NCCREATE.
mpv's mouse button numbering is based on X11, which means XBUTTON1 and 2
on Windows (the "back" and "forward" buttons) should map to MOUSE_BTN7
and 8 in mpv. MOUSE_BTN5 and 6 refer to the horizontal scroll buttons on
mouses that have them.
Windows doesn't have a way to distinguish "precise" mouse wheel events
and events from regular notched mouse wheels. A notched wheel should
always send events with a delta of 120, but a precise wheel could also
happen to send 120 if multiple scroll events are coalesced (and to make
things even harder, some buggy Microsoft drivers send deltas less than
120, even for notched wheels.) Since there is no distinction, but
MP_AXIS_* keycodes can hold more information (the delta value,) send
MP_AXIS_* events for both kinds of mouse wheel scrolling.
Previously, the shared behaviour for each mouse-button message lived at
the bottom of the WndProc. Move it into handle_mouse_down/up functions
(similar to the handle_key_down/up functions.) This makes the WndProc
slightly less complicated. There should be no change in behaviour.
The old code called reinit_window_state() from the VO thread, which is
not safe. Instead of calling reinit_window_state() when
VO_EVENT_FULLSCREEN_STATE is captured, it should be called when sending
the event from the Win32 thread instead.
This was mostly self-contained, so its removal makes w32_common.c a bit
easier to read. Also, because it was self contained and its author has
agreed to LGPL relicencing, the new file has the LGPL licence header.
According to MSDN, in WM_SYSCOMMAND messages, the four low-order
bits of the wParam parameter are used internally by the system.
To obtain the correct result when testing the value of wParam,
an application must combine the value 0xFFF0 with the wParam
value by using the bitwise AND operator.
Allow minimizing the borderless/fullscreen window by clicking on the
taskbar button or pressing Win+Down hotkey.
Also fixes#2229 and probably fixes#2451
According to MSDN, GetWindowLong and SetWindowLong have been
superseded by GetWindowLongPtr and SetWindowLongPtr.
It's a cosmetic code change in this case.
This should make display-names usable on Windows. It returns a list of
GDI monitor names like "\\.\DISPLAY1". Since it may be useful to get the
monitor that Windows considers associated with the window (with
MonitorFromWindow,) this will always be returned as the first argument.
This monitor is the one used for display-fps and icc-profile-auto.
We always want to use __declspec(selectany) to declare GUIDs, but
manually including <initguid.h> in every file that used GUIDs was
error-prone. Since all <initguid.h> does is define INITGUID and include
<guiddef.h>, we can remove all references to <initguid.h> and just
compile with -DINITGUID to get the same effect.
Also, this partially reverts 622bcb0 by re-adding libuuid.a to the
build, since apparently some GUIDs (such as GUID_NULL) are not declared
in the source file, even when INITGUID is set.
Instead of using input_ctx for waiting, use the dispatch queue directly.
One big change is that the dispatch queue will just process commands
that come in (e.g. from client API) without returning. This should
reduce unnecessary playloop excutions (which is good since the playloop
got a bit fat from rechecking a lot of conditions every iteration).
Since this doesn't force a new playloop iteration on every access, this
has to be enforced manually in some cases.
Normal input (via terminal or VO window) still wakes up the playloop
every time, though that's not too important. It makes testing this
harder, though. If there are missing wakeup calls, it will be noticed
only when using the client API in some form.
At this point we could probably use a normal lock instead of the
dispatch queue stuff.
On a VOCTRL_UPDATE_PLAYBACK_STATE store the state, and use it to
initialize the next time the task list becomes available.
This actually fixes#3482. Revert commit f2e25e9e because it's not
needed anymore.
Because VOCTRL_CHECK_EVENTS is processed asynchronously (as of 088a007,)
the GUI thread no longer gets regular wakeups, so the old check that
made sure the video window matched the parent window's size in --wid
embedding mode did not run very often. This made --wid embedding not
very usable.
Instead of polling for window size changes, use Windows hooks to react
to them when they happen. When the parent window is owned by the same
process as the video window, use a WH_CALLWNDPROC hook. When the parent
window is not owned by the same process, WinEvents must be used, which
are not as smooth, but still work for this purpose.
Since neither SetWindowsHookEx nor SetWinEventHook take a context
parameter to send data to the hook function, the hook functions must
find the child window by its class instead, so there are a few changes
to ensure this is fast and the class is unique.
This also fixes up the logic to handle window destruction. When a parent
window is destroyed, its children are also destroyed, so this gives us a
way to react to parent window destruction without polling.
VOCTRL_CHECK_EVENTS is called on every frame. This is by design, and is
supposed to check the event queue of the windowing API.
With the decoupled GUI thread in w32_common.c this doesn't make too much
sense, and the purpose of VOCTRL_CHECK_EVENTS is really reduced to
checking event flags. Even worse, waiting on the GUI thread can
interfere with playback, since win32 sometimes blocks the event loop
(e.g. clicking the window title bar).
Change the code such that we really only query the event flags. Use
atomics to avoid having to add a new mutex. (We assume we always have
real atomics available. The build system doesn't check this properly,
and it could fall back to dummy atomics, which are not atomic.)
Should help with #3393. Doesn't help if the core happens to send a
synchronous request, most commonly via VOCTRL_SET_CURSOR_VISIBILITY or
VOCTRL_UPDATE_PLAYBACK_STATE.
This makes the geometry of the sizing borders more like the ones in
Windows 10. It also fixes an off-by-one error that made the right and
bottom borders thinner than the left and top borders, which made it
difficult to resize the window when using the Windows 7 classic theme
(because it has pretty thin sizing borders to begin with.)
This is a common idiom used in MSDN docs and Raymond Chen's example
programs to get a HINSTANCE for the current module, regardless of
whether it's an .exe or a .dll. Using GetModuleHandle(NULL) for this is
technically incorrect, since it always gets a handle to the .exe, even
when the executing code (in libmpv) is running in a .dll. In this case,
using the wrong HINSTANCE could cause namespace issues with window
classes, since CreateWindowEx uses the HINSTANCE to search for the
matching window class name.

Position the window around the original window center on video size change
(when switching to the next file with different resolution, for example)
instead of keeping the position of its top-left corner fixed.
Before that position of the window top-left corner was remaining the same
when the window was scaled.
Right now VOCTRL_SET_UNFS_WINDOW_SIZE is called only by window-scale. This
change will not affect resizes made by the user (dragging window edge).
Fixes#3164.
Center the window on the original window center instead of the screen center
when the window has been resized due to requested window size exceeding the
size of the screen.
If user moved the window, he probably did it for the reason and he probably
don't want it to get back to the center of the screen when he is resizing it
(with window-scale for example).
Properly update stored client area size when the window is resized in
reinit_window_state due to window size exceeding the size of the screen.
This was causing wrong behavior with window-scale - when window size was
becoming too big the window was resized but the video was not.
Add --taskbar-progress command line option and property which controls taskbar
progress indication rendering in Windows 7+. This option is on by default and
can be toggled during playback.
This option does not affect the creation process of ITaskbarList3. When the
option is turned off the progress bar is just hidden with TBPF_NOPROGRESS.
Closes#2535
Including initguid.h at the top of a file that uses references to GUIDs
causes the GUIDs to be declared globally with __declspec(selectany). The
'selectany' attribute tells the linker to consolidate multiple
definitions of each GUID, which would be great except that, in Cygwin
and MinGW GCC 6.1, this method of linking makes the GUIDs conflict with
the ones declared in libuuid.a.
Since initguid.h obsoletes libuuid.a in modern compilers that support
__declspec(selectany), add initguid.h to all files that use GUIDs and
remove libuuid.a from the build.
Fixes#3097
Substraction of 1 is not necessary due to .right and .bottom values of RECT
struct describing a point one pixel outside of the rectangle.
Fixes#2935. (2.b)
This is the "unicode" version of it. It appears Firefox uses it now?
I'm not sure if we still need to support the old variant, but hopefully
not.
